Letter Patent No. 76,966, dated April 21, 1868 IMPROVEMENT INLAMP-BURNERS.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, JOHN R. AcKEnMnN, EDWARD BKCAMPBELL, and NIRAM O.GOLDEN, of Dobbs Ferry in .the county of Wcstchester, and State of NewYork, have inrented a 'new and improved Lamp-Burner; and we db herebydeclare that the-following is a full, clear, and exact descriptionthereof, which will enable those skilled in the art to make and use thesame, reference being had to the accompanying drawings, forming part ofthis specification.

This invention relates to improvements in that-class of lamps in whichkerosene-oil orother hydrocarbonoils or liquids are burned,. and whichrequire a chimney tosurrou'ndthe flame in order to produce a perfectcombustion, and prevent smoking. And it consists in the application andarrangement of a double cone, or cons and cylinder, which surrounds thewick-tube of the lamp, whereby'the flame is supplied with atmosphcricair or oxygen in sufficient quantity to produce perfect combustion,and'prevent smoking, without the use of a chimney;

as will he hereinafter more fully described. I

Figure 1 represents an outside view of. theburner of a kerosene-lampconstructed accord-ingto our invention.

Figure 2 is a vertical section of the same through the line a: :0.

Similar letters of reference indicate correspondingpa rts. I

'A is the ordinary wick-tube, and Bis the haseof the burner, whichscrewsinto the neck ofthe lamp. This part of the burner is made in theusual manner, only the tube A is elongated, as seen in the drawing.

0 is acone surrounding the tube, which is open around the base for theadmission ofair, as seen at d, and also open at its top end above thewick'tubc, as seen at e. 1

The curve at the .upper end of the cone conducts the current of air,which ascends within the cone, directly to the'wick andfiame ofthe lampat the base of thefiame. v I

D is a section of a'cylinder with its lower end serrated, and its upperend conical in form, and open, as seen in the drawing. p T

In this example'of our'invcntion, the pointsf of the cylinder D areattached to the cone G, which leaves .open spaces between the points forthe admission of air.

The cylinder is-also perforated below the conical top for the purpose ofgiving access to the air.

The air thus admitted within the cylinder D, is, by the conical top E,brought in direct contact with the flame of the lamp. This cylinder Dmaybe constructed in different ways or shapes, and attached to theicone.Olin a difi'crent manner from that shown.' 7

The perforations may be dispensed with, if desired, and other andadditional provision may bemadc for the admission of air at its lowerend or through its sides.

We are aware that many experiments have been made, (we have made manyourselves,) with a view to doing away with the-very objectionablelamp-chimney, but hitherto 'no plan,.(as far as we are aware,) hasproved successful. A

We can account for this in no way but upon the supposition that thecarbon of the burning oil and the oxygen of the atmosphere have notbeencombined in-pr'opcr proportions nor properlyunited to produce perfectcombustion.

- We, in the course of our experiments, have found that by extending thewick-tube, and surrounding it with i a double cone, or cone andcylinder, or with two cylinders arranged substantiallyas we-havcdescribed, we accomplish the object sought. 1

By the arrangement shown, an upward current of air is produced which notonly supplies the flame with the requisite quantity of oxygen, butsupplies it at the right time andplace.

Having thus described our invention, what we claim as new, and-desire tosecure by Letters Patent, is-

The arrangement of the perforated cylinder D with relation to theopcmbottomed cone'U, conical top E and wick-tube A, as herein described,for the purpose specified.
